ATTACHMENTS OF CHEST MUSCLES

 * A lady between two majors.
 * Pectoralis major attaches to lateral lip of bicipital groove.
 * Teres major attaches to medial lip of bicipital groove.
 * Latissimus dorsi attaches to the floor of bicipital groove.
 * The "lati" is between two "majors."
 * "Lateral is less, medial is more."
 * Lateral pectoral nerves goes through pectoralis major while medial pectoral nerve goes though both pectoralis major and minor

CRANIAL NERVES
I - olfactory, II - optic, III - oculomotor, IV - trochlear, V - trigeminal, VI - abducens, VII - facial, VIII - acoustic (vestibulocochlear), IX - glossophrayngeal, X - vagus, XI - accessory, XII - hypoglossal

Deep Reflexes
Biceps (C5-6) elbow flexion

Brachio-radialis (C5-6) elbow flexion & supination

Triceps (C7) elbow extension

Patellar (L3-4) knee extension = knee jerk

Achilles (S1) plantar flexion = ankle jerk

LR6 SO4 R3

 * LR6 - Lateral Rectus --> CN VI Abducens
 * SO4 - Superior Oblique --> CN IV Trochlear
 * R3 - The Remaining 4 eyeball movers --> CN III Occulomotor
 * or LAST: LA = Lateral Rectus - Abducens Nerve, ST = Superior Oblique - Trochlear Nerve

BRANCHES OF FACIAL NERVE
Temporal, Zygomatic, Buccal, Mandibular, Cervical


 * Two Zebras Bought My Car
 * Two Zebras Bit My Cookie
 * To Zanzibar By Motor Car
 * Ten Zulus Buggered My Cat
 * To Zionsville By Max's Car
 * Tappan Zee Bridge May Close
 * Two Zombies Bit My Cranium

CERVICAL SPINAL NERVES

 * c345 keep the diaphragm alive (innervation of diaphragm by the phrenic nerve)
 * c5-6-7 raise your arms to heaven (nerve roots of long thoracic nerve innervate serratus anterior and if severed you see "winging" of the scapula)

INNERVATION OF PENIS

 * Parasympathetic causes erection. Sympathetic causes ejaculation. "Point and Shoot."
 * "S2, 3, 4 keep the penis off the floor"
 * Innervation of the penis by branches of the pudendal nerve, derived from spinal cord levels S2-4

AORTIC BRANCHES

 * ABC'S
 * Aortic arch gives off the Brachiocephalic trunk, the left Common Carotid, and the left Subclavian artery

Order of things in the Femoral Triangle
NOTE: Parenthesis includes things contained in the femoral sheath. LOCATION OF INQUINAL HERNIAS with Reference to the Inferior Epigastric Arteries:
 * "N(AVEL)" (From Lateral To Medial)
 * Nerve, Artery, Vein, Empty space, Lymphatics
 * "MDs don't LIe" (Medial- Direct, Lateral - Indirect): Direct inquinal hernias are Medial while Indirect hernias are Lateral to the inferior epigastric arteries
